    CVD diamond tools generate poor surface finish compared to PCD due to rough coating surfaces. Though post-deposition polishing of the coating may improve part surface finish (Arumugam et al., 2006), the additional step is expensive and difficult to perform on complex shapes. On tool life, there are, however, mixed results of CVD diamond performance.
